Ulva Lactuca represents a great natural resource that occurs spontaneously in the Lake of Ganzirri, but its sustainable use and possible effectiveness can be exploited? This seaweed contains a significant amount of micro- and macronutrients such as minerals, trace elements, vitamins, essential amino acids, antioxidants, and many bioactive compounds, which can be extracted to develop new food supplements. In fact, the antioxidant, anti-inflammatory and antimicrobial properties make it useful for both the pharmaceutical, food and cosmetic fields. Ulva Lactuca is beneficial for boosting mental and physical energy, promoting tissue hydration and elasticity, treating premenstrual syndrome, and preventing bone loss.
